The UCD National Virus Reference Laboratory (NVRL) provides a diagnostic and reference service for clinicians investigating viral infections throughout Ireland. The laboratory is affiliated to the University College Dublin School of Medicine. The NVRL have provided a virology diagnostic service to the Irish health service for over forty years. We currently perform over 700,000 tests annually, involving some 120 tests for 40 different pathogens and provide specialist reference services which have been developed as a result of medical and technical expertise built over many years. We are proud to offer our service users accredited tests in line with national and international "best practice".
